Abstract
A cascade refrigeration system wherein the inlet and outlet pressures and the power consumption of the compressor of the higher temperature refrigeration circuit, and the inlet and outlet pressures and the power consumption of the compressor of the lower temperature refrigeration circuit are ascertained and used to calculate more efficient operating pressures, and the operation of the compressors is adjusted to adjust the pressures of the incoming refrigerants to the cascade heat exchanger toward the more efficient operating pressures.
